Description

[Detailed explanation of the idea] The present invention relates to an operation display mechanism for a hot water mixer faucet.

Conventionally, U.S. Patent No. 39942 was used as an operation display mechanism for faucets.
There is one shown in Figure 4 of the specification of No. 55.

To explain this, a skirt-shaped display member 22 that is attached to the upper surface of the bundle 20 and has a vertical groove 21;
A ring 25 that is rotatably attached to the main body 23 and has a protrusion 24 that engages with the vertical groove 21 forms an operation display mechanism. The operating status of the valve portion 26 is displayed by changing the relative position with respect to the vertical groove 21.

However, in this case, the protrusion 24 and the vertical groove 21 of the display member 22
Due to the friction generated between the inner surface and the ring 25 and the main body 23, the bundle 20 is difficult to operate and also generates friction noise.

In order to solve this drawback of US Pat. No. 3,994,255, a flange portion is provided protruding from the upper surface of the main body as described in Utility Model Publication No. 1635/1983, and a display piece is screwed to the flange portion. There is something.

However, the main body of the device disclosed in Japanese Utility Model Publication No. 1635/1983 is large due to the presence of the flange, and it is easy to get your hand caught between the lever and the flange, and it is troublesome to screw the display piece, and the head of the screw is large. The disadvantage is that the part protrudes above the display piece and obstructs operation.

Therefore, the technical problem to be solved by the present invention is to attach a display piece to the side peripheral surface of the main body surrounding the spindle.

In order to remotely solve the above-mentioned technical problem, we will introduce a hot water mixer faucet body with a valve inside, a spindle with one end connected to the valve part and the other end protruding from the hot water mixer faucet body, and this spindle. An operation display mechanism for a hot water mixing faucet, comprising an operation bundle provided with a lever attached to the other end and extending laterally, and adjusting the mixing ratio of hot water and water at a valve part according to the rotation angle of the operation bundle. and a display piece is mounted on the hot water mixing faucet body, which is formed into a substantially cylindrical shape and has a band-shaped annular step portion on the outer circumferential surface of the upper end thereof and a notch carved in the step portion, and the spindle protrudes from the upper end surface. A metal plate is provided on the outer circumferential surface of the stepped portion of the display piece mounting portion with a metal plate having a thickness approximately equivalent to the depth of the stepped portion and a width approximately equivalent to the vertical width of the stepped portion. A display piece shaped like a protrusion that protrudes into the notch and engages with the notch is fitted, and the operation bundle covers the upper end surface of the display piece mounting part, and the outer peripheral surface of the display piece is fitted with a display piece shaped like a protrusion that engages with the notch. The operating status of the valve portion is determined in accordance with the direction of the lever.

Therefore, the main body does not become large, and the user does not have to pinch his/her hand when operating the lever, and does not get in the way of operating the lever.

Since the present invention has the above configuration, it has the following advantages.

An indicator mounting portion having a belt-shaped annular step and a notch formed in the step is provided on the outer circumferential surface of the upper end of the hot water mixing faucet body, and an indicator mounting portion is provided on the outer circumferential surface of the stepped portion of the indicator mounting portion. Since the display piece formed with the engaging protrusion is fitted and the upper end surface of the display piece mounting part is covered with the operation bundle, the display piece can be easily attached to the hot water mixer faucet, and the display piece can be easily replaced. I can do it.

Furthermore, the display piece does not shift due to the engagement between the notch and the protrusion, and there is no possibility that there will be a discrepancy between the displayed information and the actual operation.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

A in the figure is a hot water mixing faucet, the main body 1 of which is provided with a display piece mounting part 13 projecting in a substantially cylindrical shape on the upper surface, and an opening 2 at the end of the display piece mounting part 13. is operation bundle 3
is in place.

The operation bundle 3 is formed in a cylindrical shape, and is integrally provided with a lever 6 extending laterally on its side peripheral surface, and a spindle 4 extending into the main body 1 through the opening 2 is connected to the lower surface. It communicates with the valve section, that is, the valve body 5, through the lever 6, and the valve body 5 is rotated by rotating the lever 6.

The valve body 5 is made of a ceramic (alumina porcelain, etc.) plate and is configured to adjust the mixing ratio of hot water according to the rotation angle of the operating bundle 3, and the lever 6 of the bundle 3 is located on the left side when viewed from the front. , that is, in Figure 1, a
When it is in position , both hot and cold water are closed, and when it is in position b, which is slightly to the right, only water is supplied, and when it is in position C, hot water and water are mixed in an appropriate ratio. Furthermore, when moving to a position closer to the right, that is, position d, only hot water is discharged, and the amount of water discharged in the process of moving from position a to position d is increased, or the amount of water discharged is approximately constant. The mixing ratio of water and hot water is temporarily changed while maintaining the same temperature.

In addition, an annular stepped portion 8 having a notch 7 is formed on the outer peripheral surface of the opening 2 of the display piece mounting portion 13, and the iron portion indicates the position of the lever 6 of the operation bundle 3 and the state of the discharged water, that is, the discharged water is cold water. A display piece 9 is attached to display whether the water is hot water, moderately mixed water, or hot water.

The stepped portion 8 is formed in the shape of a band on the outer circumferential surface of the opening 2 over the entire circumference in the circumferential direction, and is recessed one step from the other portions by an appropriate width from the upper end. It is formed by partially cutting out a length corresponding to the width in the vertical direction.

The display piece 9 is formed by press-molding a metal plate such as an aluminum plate having a thickness corresponding to the depth of the step part 8 and a width corresponding to the vertical width of the step part 8.
It is formed into an annular body having an inner diameter corresponding to the outer diameter of the part, and a part thereof is formed with a protrusion 10 projecting inwardly, a necessary marking 11 is made on the surface, and a clear coating is applied.

The protrusion 10 is formed by recessing a part of the display piece 9 inward across a width corresponding to the width of the notch 7 provided in the opening 2.

The display piece 9 is fitted into the step 8 provided on the outer periphery of the opening 2 of the display piece mounting portion 13, and the protrusion 10 is inserted and locked into the notch 7, thereby forming the step on the surface of the display piece mounting portion 13. Can be installed over 8.

For example, the display 11 may be closed indicating that the discharge is stopped, or 5 on the part of the display piece 9 that corresponds to the position of the lever 6 of the bundle 3 when the discharge is stopped, that is, the position a in FIG.
Letters such as HUT are applied, and the position of the lever 6 when only cold water is being discharged, that is, the part corresponding to position b, is blue to represent cold water, and the position of the lever 6 is C when discharging hot water at an appropriate temperature. The part corresponding to the position d of the lever 6 when discharging hot water is colored orange or red to indicate hot water. Make it possible to judge the water condition at a glance.

The form of the display 11 may be a combination of letters and arrows in addition to this embodiment, and the form is arbitrary.

In addition, this display 11 can be applied by any method such as baking, printing, engraving, labeling, etc. on a metal plate, but since it is a display mechanism for equipment that easily gets wet with water, hot water, etc. It is necessary to apply it in a way that prevents it from peeling off or burning out.

In the advance sale example, the display piece mounting portion 13 was provided with one notch 7, and the display piece 9 was provided with one protrusion 10, but the present invention is not limited to this. It may be provided.
